<span>x= 5 + y
28x – 9y = -12
substitute </span>x= 5 + y into 28x – 9y = -12
28x – 9y= -12
28(5 + y) – 9y = -12
140 + 28y - 9y = -12
19y = -152
y = -8
<span>x = 5 + y
</span>x = 5 - 8
x = -3
solution (-3, -8)
Step-by-step explanation:
5(2a - 6) + 3a
10a - 30 + 3a
13a - 30
right
Hello :
<span>h(x) = 6x² − 60x + 147= (x² -2(30)x+30²)-30²+147
</span>h(x) = (x-30)²-753 .....(vertex form)
<span>the axis of symmetry is the line of equation : x=30</span>
Answer:
I'll do the first one as an example. The answer of the first one is 6.
Step-by-step explanation:
In the first example, they multiplied the number by 2 to get a common denominator for the two fractions so you can easily add. So, the first box will come 10 (5 times 2) and the second box will become 2 (1 times 2). Then simply add the fractions. The sum of the first question is 2. Because 2 10/12 + 3 2/12 = 6. Remember to add only the whole numbers and fractions. If you want, you can try using mathaway for additional help.
Hope this helps a little more.
